Atmospheric pressure liquid filling machine is filled by liquid self-weight under atmospheric pressure. When the machine is in the “automatic” state, the machine automatically fills continuously at the set speed. When the machine is in a “manual” state, the operator steps on the pedal to achieve filling. If the machine keeps stepping on, it will also become a state of automatic continuous filling. This kind of filling machine can be divided into regular filling and quantitative filling. It is only suitable for filling low viscosity and gas-free liquids such as milk and wine.

Working Principle: The material flow direction is controlled by one-way valve, and the cylinder stroke is controlled by magnetic spring switch, so the filling quantity can be adjusted. The filling machine now generally adopts the flow meter filling mode. Lubricating oil has its own unique characteristics. The corresponding requirements for filling machine are more stringent and relatively expensive. Therefore, the accuracy of filling machine is relatively high. Generally, the accuracy of filling machine needs to reach 0.2%. Lubricating oil filling machine is usually equipped with temperature tracking system to maintain the stability of measurement accuracy.
